Mozambique

Status: affected by circulating vaccine-derived poliovirus type 2 (cVDPV2) 

Circulation of vaccine-derived poliovirus type 2 (cVDPV2) has been confirmed in Mozambique.

The detection of cVDPV2 underscores the importance of maintaining high routine vaccination coverage everywhere to minimize the risk and consequences of any poliovirus circulation. A robust outbreak response is needed to rapidly stop circulation and ensure sufficient vaccination coverage in the affected areas to prevent similar outbreaks in the future. WHO will continue to evaluate the epidemiological situation and outbreak response measures being implemented.

International Health Regulations

Mozambique is classified by the International Health Regulations (IHR) as a state infected with cVDPV2, with potential risk of international spread.  It is therefore subject to temporary recommendations as of September 2019.

Travel advice

WHO’s International Travel and Health recommends that all travellers to polio-affected areas be fully vaccinated against polio. Residents (and visitors for more than 4 weeks) from infected areas should receive an additional dose of OPV or inactivated polio vaccine (IPV) within 4 weeks to 12 months of travel.
